Matthew 12:24-27

24 The Pharisees also heard about what had happened. They said, ‘This man can send demons out of people only because Beelzebul gives him authority. That is Satan, the one who rules all the demons.’

12:24Beelzebul is another name for Satan.

25 Jesus knew what the Pharisees were thinking. So he said to them, ‘If armies in a country fight each other, then they will destroy their own country. If people in one city or in one family fight each other, then they will destroy their own city or family. 26 So Satan would not try to destroy himself. If Satan fights against himself, that would be the end of his own kingdom. 27 Some of your disciples can also send demons out of people. You would not say that it is Satan's power that helps them. So your own disciples show that you are wrong about this.
